How is Alzheimer's disease treated?
Senile dementia, also known as Alzheimer's disease, is the most common neurodegenerative disease worldwide. The pathogenesis of this disease is not particularly clear so far and may be related to genetic and environmental factors. Multiple factors act on neurons causing irreversible and progressive death of neuronal cells. Currently, the treatment of this disease mainly includes two aspects. The first aspect is general treatment, mainly including family care. Family members must pay attention to the care of the patient, prevent the patient from accidentally wandering off, prevent the patient from falling, and prevent some accidents that cause injuries. In addition, it is important for the patient to listen to music, interact with others, and exercise more, all of which can delay the progression of senile dementia. The second aspect is pharmacological treatment, mainly using drugs that inhibit the reduction of acetylcholine. These drugs can increase the content of acetylcholine and improve the cognitive functions of patients to a certain extent, but so far, these treatments cannot reverse senile dementia.
What does stroke include?
Stroke, translated from the English word "stroke," refers to rapidly occurring pathological changes. Stroke mainly includes two types of diseases: ischemic cerebrovascular disease and hemorrhagic cerebrovascular disease, with ischemic cerebrovascular disease being the most common. Ischemic cerebrovascular disease includes large artery atherosclerotic cerebral infarction, small artery occlusive cerebral infarction, as well as cardiogenic cerebral embolism and other causes of cerebral infarction. Hemorrhagic cerebrovascular disease mainly includes cerebral hemorrhage caused by hypertension, subarachnoid hemorrhage, and cerebral hemorrhage caused by aneurysms or vascular malformations. The onset of a stroke is very aggressive and can severely threaten the patient's health. Once a stroke is suspected, it is critical to rush to the hospital for appropriate diagnostic tests to confirm the diagnosis and provide the most suitable treatment plan.
Difference between Vertigo and Otolithiasis
Vertigo encompasses a broader concept, including conditions like benign paroxysmal positional vertigo (BPPV). Any disease that can cause patients to experience symptoms such as dizziness, spinning sensations, nausea, and vomiting, can be referred to as vertigo. BPPV is simply one common cause of vertigo. It primarily results from otoconia forming in the vestibule's semicircular canals or the utricle and saccule. These otoconia shift with head movements, disrupting the inner ear's lymph fluid, leading to transient episodes of vertigo closely related to body position changes. These episodes, lasting several seconds, can be completely alleviated and are considered a type of vertigo. Additionally, vertigo includes diseases like vestibular neuronitis and Ménière's disease. Therefore, the concept of vertigo is quite broad, and it is crucial to accurately diagnose the cause of vertigo in clinical practice to provide targeted treatment.
How to medicate for the rigidity in Parkinson's disease?
Parkinson's disease presents with rigidity, mainly due to increased muscle tone and muscle rigidity, which is a very important clinical manifestation of Parkinson's disease. The medications used for rigidity in Parkinson's disease mainly include the following types. The first type is dopamine receptor agonists, which can improve limb muscle rigidity to some extent and delay the progression of the disease. The second type of medication is levodopa preparations, which are currently the gold standard for treating Parkinson's disease. Many patients experience significant clinical improvement after taking the medication. The third type of medication includes some anticholinergic drugs. These drugs are particularly effective against tremors and also have some effect in improving rigidity. Medication for Parkinson's disease must be taken under the guidance of a doctor. It is also important to note that levodopa preparations should be taken on an empty stomach or two hours after a meal for better efficacy.
Can encephalitis be cured?
Encephalitis is divided into many types. If it is a simple herpes virus encephalitis infection, this is a rather dangerous type of encephalitis. Before the advent of antiviral drugs, the mortality rate of this type of encephalitis was very high. Now, with improvements in diagnostic and treatment levels and the development of antiviral drugs, the prognosis for this type of encephalitis is generally quite good. As long as the initial condition is not particularly severe, the patient is not in a coma, or there is no obvious continuous epileptic state, the prognosis is still good, and many patients do not have any residual sequelae. However, if the initial condition is quite severe, there is usually some degree of cognitive impairment or weakness in the limbs. Other viral encephalitides, such as those caused by Coxsackie viruses and adenoviruses, tend to have milder symptoms, mainly fever, headache, nausea, and vomiting. These types of encephalitis can mostly be cured with appropriate symptomatic treatment and antiviral therapy.
Where to treat Parkinson's disease
Parkinson's disease is a very common neurodegenerative disease in neurology. Therefore, if Parkinson's disease is suspected, treatment can be sought in the neurology department, which is available in most hospitals. Many neurologists have extensive experience in treating Parkinson's disease. The treatment primarily includes medication and surgery. Medication therapy mainly refers to the administration of anticholinergic drugs or dopamine receptor agonists, as well as preparations of Levodopa. These medications can help improve symptoms, such as reducing muscle rigidity and tremors. Surgical treatment mainly refers to deep brain stimulation, which is suitable for patients who have been clearly diagnosed with Parkinson's disease for over five years and whose primary symptom is tremor, without significant dementia.
Where does the migraine hurt?
The location of migraine pain is generally most commonly on one side, particularly in the frontal and temporal areas, which are the temples. Patients may feel a distinct pulsing in the blood vessels, and the pain can be quite severe, accompanied by significant nausea, vomiting, and other symptoms. However, some migraine sufferers experience bilateral pain in the frontal and temporal areas, meaning both temples feel significantly painful. The treatment primarily involves administering non-steroidal anti-inflammatory pain medications. If the patient also experiences significant nausea and vomiting, these symptoms need to be addressed as well. Additionally, migraine sufferers tend to be very sensitive to strong light and sound stimuli; it is recommended that they rest in bed during a migraine attack. If migraine attacks are frequent, it is advisable to take preventative medications orally.
Optic neuritis hormonal side effects
Optic neuritis is a demyelinating disease caused by an inflammatory response, a disorder resulting from an immune dysfunction of the body. Thus, corticosteroids play a critical role in its treatment, and are widely used clinically. However, corticosteroids also have some side effects, such as causing osteoporosis, decalcification, and even necrosis of the femoral head, leading to significant obesity in patients due to redistribution of some fats, resulting in conditions like moon face and buffalo hump, and other adverse reactions including acne. Additionally, corticosteroids can have stimulating effects, potentially causing symptoms like insomnia and tachycardia; they also have gastrointestinal side effects, leading to acute ulcers and gastric mucosal lesions.
Can cerebral embolism be treated with thrombolysis?
For patients with cerebral embolism, if the onset is not particularly severe and the area of the embolism is not very large, for example, if the patient's consciousness is still clear, then thrombolysis can still be feasible. It is now also relatively advocated because the risk of cerebral hemorrhage is relatively small in such cases. However, if the area of the cerebral embolism is large, especially if the patient has fallen into a coma or other consciousness disorders, and shows conjugate gaze palsy, then the risk of thrombolysis is very high, and there is a very likely risk of conversion to cerebral hemorrhage. In such cases, thrombolysis is not recommended, and arterial thrombectomy can be performed instead, which can greatly save the patient's life and improve the quality of life. Besides thrombolysis and thrombectomy, anticoagulant therapy should also be administered after the condition stabilizes, as most cases of cerebral embolism are caused by atrial fibrillation, and anticoagulant therapy can prevent future attacks.
What department to see for Parkinson's disease?
Parkinson's disease is a very common degenerative neurological disorder in neurology, so if you go for treatment, you should definitely see a neurologist. Many neurologists have a high level of expertise in Parkinson's disease and have extensive experience in its diagnosis, differential diagnosis, and treatment. Patients with Parkinson's disease generally exhibit significant motor slowness, such as dressing, buttoning, wrapping dumplings, and eating very slowly, and they also walk very slowly. In addition, they may also display obvious resting tremors, muscle rigidity, general fatigue, unstable walking posture, and other clinical manifestations. Moreover, they might experience some constipation, anxiety, depression, and reduced sense of smell among other related clinical symptoms. Therefore, for this disease, visiting a neurologist is sufficient, and you can definitely expect a very satisfactory diagnosis and treatment.
